The request header are changing to https from http when fetching image

We have some image resources stored in one drive with the schema “http” header(e.g. “”). These images are not accessible in “https” header(e.g. “”).

I use TWC to display the images and I found the image request was changing to “https” scheme automatically. So that our images resources cannot display correctly. Could you tell me why the schema is changed when sending the request?
Below is an example which shows the image request changing from http to https.

Best regards


This is because that this page is loaded over security link (HTTPS:), while you are requesting an insecure element, it will be automatically upgraded to HTTPS. See this link for more information: Chromium Blog: No More Mixed Messages About HTTPS
